I need 2 more elbows and 2 lengths of SS Pipe. $20 scored me this heavy duty shelf to scrap for steel, plus end up with a good work table since I only need the bottom shelf to build a box around the 70ft of coil. I'm gonna put the coil in the center of it, fill it with sand to store and transfer heat, and mount it in the middle of a cement firepit.

No chimney means I can burn anything from leave to pine logs, and I've got a small tree farm fifteen miles from me with an endless supply of fuel..

Add a very small sump pump to a hotwater rated hose to one end of the coil and set it in the pool, and run a second hose from the outlet side and eventually I'll add a sensor to shut the pump off when the water cools down.

Also the firepit will be at about the same level as the bottom of the pool, and hot water rises, so next year when we burn leaves we should be able to heat the pool right before we open it, and the black winter cover had it at 84 degrees, plus we can keep it warm long after fall gets here so Mary can excersise a bit

Since it's lower I'll also be able to build an emergency out door shower if we lose power for a long time, and draw both hot and cold water to it from the pool, which is in ground and has a good chance of surviving, or else just hook it to the well which has it's own generator, already checked them for hurricane season 2013.

Re: John

Thought I was unscreening comments but was actually screening them instead.

I'm covering the pool for the winter cause the acorns are falling here but will hopefully be able to get the SS steal piping from the pool to it and back to the pool tig welded and hope to be burning leaves in it and getting some free heat.

Heavy cover and dark to grab heat from the sun so it will be an excellent time to actually do a test of how fast it can raise the pool temp a degree.
